Can you delete the thumb file in the general folder?

This is a cache file generated by viewing thumbnails. This is a normal phenomenon, not a virus. If it does not appear, you can: Control Panel-Folder Options-View? In the advanced settings, select the "Do not cache thumbnails" option.

You can also open the running window of the start menu, go to gpedit.msc, open Group Policy Configuration, User Configuration-Management Template -Windows Components -Windows Explorer, and find and double-click the strategy to open and close the thumbnail cache in the right window.
